To all whom t may concern.' y

Be it known that .Wej JOHN' F. GArL and CHARLES H. BUSCH, citizens of the 'of rig. i.

United States,` residing at Evanstomin the county of Cook and State of Illinois, and at Kenosha, in the county of vKenoshaand `State of TWisconsin, respectively',A have in-A vented certain new and v useful Improvements in Bedstead Coiner'Locks .ofvhich thefollowing is a specification.

Cuiinvention relates `to improvementsl in bedstead corner locks and refers to. atype of corner lock used for: connecting thefhead end andfoot end of abedste'ad by. means of side rails preferablyof angular cross section. Y l y i A' The principal "objects Of our invention are to 'providef'a' rcorner lockl Which may be constructed. of Stamped*V sheet metal. or krolled shapes; to lprovide a construction 'which Will admit of the use of a side railhaving an angular cross section throughout its length, and having its ends devoid ofY projeetinglparts; Vto provide a corner lock `of "theftypedescribed `which 'may be disconnected from the bedstead'endframe Without the use' 'of special tools yor appliances and which may be assembled with equal facility; to provide a cornerlock having attaching and adjusting means ac cessiblefroni 'the exterior of the bedstead; to provide a corner lock which vshall-.be rugged and substantial iii constructionV WhileA being simple and economical in design and manufacture,y and Vin genera-l, to provide an improved elicient corner lock ofthe character referred to. ln-.the draving'sy which illustrate a specific Vapplicationv of our invention .to a tubular `metallic bedstead l f VI'Fi'g.1. is a side elevation of thecorner lock Showing the bed post andthe side rail connected thereto by our -improved 'cbrnerlocln Fig; 2 is a sectionV taken on Fig. 3 is a section taken on the line ofl Fig. 2. l'

Figli isa plan view-of theV corner lock, and A Y i' Fig. 5 isv a perspective view of a stiffening member.

VReferring to the drawingsfit Will be observedthat although We have not shown a Complete bedstead, it Will be understood that the Vbedstead frame "comprises theusual four corner posts, one of which 'H10 is v shownV fragmentarly, vthe corner posts onV the saine Side ofthe bedstead being con- 1 nected by side rails, one of Which is shown at 11. ln the particular bedstead to Vwhich our improved corner locl is'shovvn applied,

the post v10 is of tubular form, its cross section being substantially that of a. square,

preferably is' of angle iron construction as best shown in Fig. 2 ofthe'dravvings.

VThe* Vpurpose of the :corner lock Vis to Vas indicated in Figl. The siderail 171 connect the end of. the angle iron 11 to KQ.,

Vend through aver-tical v.plane in order tjoY 4the'cor'ner post 10 of: thelbedstead frame, Ythe 'arrangement b'eingpreferably such that bring` the lhoriZontial-'fflange 12v of the'vside 'rail either atthe top of the 'vertical flange A' 12 or ati the bottom thereof. Such reversible. construction is: des-irableto enable the saine bedstead frame to be Afused with bottoms or springs of different Vtypes as is vvell l understood by those Skilledinthe art.'

T he corner lock` herein 'l shown is-in theV nature of a development or anv improvement on' `the corner lock illustratedand vvdescribed in Frank Kusterle',v Patent No. 11,411,362,

dated April 4, 1922,vvhichV iso'vvned by the Vassigmee of this application.

Well adapted, the Side rail 11-is insertable .into a socket having apair of` Optional 'corner seats for receiving the end vofthe angle iron andequippedyvith suitable Wedg ing or clamping' means for detachably securingthe end ofthe angle; iron rigidly i.

Ain the socket. VAS shown in the drawings section, 4the top 14: ofthe U being horizontal and the legs 15 `and 16 -thereof 'depending from the part A14 lin vertically parallel relation. The lpart 14 andthe upperportions of the spaced sides 1 5 and llliconstitute threek sides of fthe rectangularI .socket7 the remaining or'fbottom sideof Vthe socket l Vbeing formed by the end'of'a cross 'rail or tie member 17, which connects Atogether the two'posts of the bedstead ,endg

The railfl? besides servingas af'co'nne'ction between the two corner posts. and. as one side` of the rectangular side railjso-ket, also serves to connect together in properly spaced Y relationthe lower ends of .the side members 'ndnl'offthe socketstamping. To this'end theiianges v18"and19"o-said cross angle 17 are shouldered or reduced in width as shown at 20 in order to pass through fan L shaped opening punched in the side wall 16. the shoulder 20 being effective Vto Iprevent. outward., movementy of l the vside member 16 j away lfrom Athe 4side member 15. The 'exx'. lf ,L V: 'i ltreinity of the said angle iron 1771s further reduced in Iwidthto pass through a smaller L`shapd opening punched 1n the side member 157 the'reduced extremity being ot "sufficient lengthto enable it to be riveted over'to form yan,L enlarged Lshaped head vas bestvatf21 inig. 1.v It will be understoodV that the plate '151s thus ri'g'gidly locked 'to the extremity ofthercross angle 17,'out-k wardQmove/mentof theplate 15 being prevented'by the head 21 andinivard movement of @the plate, with` 'reference Vto the Lcross 25 l anijle lieingpevented the shoulder 22.

The socket asia whole isfdetachably seaired to the bouw-heupen 110 by means of a Iholt ory capjscrew 23, said cap screw passing freely "through an aperture ,24

'punched 'in 'thermes langie, een't'miiye of the speket la-i'rd"through 'apertures `V25 `27 punched respectively in the wall 26 ofthe 'post and'in the `sti'elaning, plate which platepeferably 'is interposed; between the abutting edges ofjthejstamping and therei- Aatively, thin post-'wall 26.,

Y bolt o'rscrew'23 its inner end suitably threadedto 'serew into a liner-,plate eiiing lplate 28 ahdp'said'liner l29. 'Prei'erf ably the` plates'28 and 2'9 extend Ivertically distance'isubstantially corresponding with the ,ilgllhpvertically ,of the socket;y and, if desired= mayy be. niadeofflengthsvfof 'rolled metal. Qn the side edges i'vthe'fouterstiii'- lening 28 there are pairs ofvrudimentaryv flanges 29 and30, `whichserve t'o ac- Acuratelyj'position "the"post and the socket relativet'o eachother,-y afnd prevent skewing of socket on the post.A Also,l we prefer to make the width' of theliner '29 such: that it may' b er readilyr inserted in the post'while at the saine time itiswide' enough to provide vthe, 'ln'axirnumlstiffenrng rY clamping effect.

' casionally yassembled' persons' having Vlittle -Yor 'no mechanical sliill f and `judgment 'and because lof the' relative' thinness 'oi'k the lcross @angle 17there'rnay be at'tim'es a tendency Y lto `bend' or buckle thepenvdl'of thecr'ossangle 17 when.' tightening up the. boit', 01rsere'w es in assemblingf'the corner lock. order to avoid this possible tifouble.'we prefer tov emplsoy'a stiieningwa'sher 3.1" punched to admit lloosely the screw 23 andxinterposed between the extremity oft-he angle iron and the head 32 of said bolt. f Y Y In order to, avoid the necessity tmakind the st-iffening washer 310i' excessive thickness itma be'iormed'offa'short length of angle iron t e'horizontal flange 33 of thelangle iron being of slightlyless depththan` Sufficient to engage the liner'28. The stilen-` Ving washer .31 also serves as a spacing mem-Y ber or'holding apart the 2lower ends .of the side walls`15 and 16 oithesocket7 it being understood 'that although the sidelplatel is prevented from moving outwardly bythe shoulder l20, there lis no internal shoulder for preventing the v'side wall 16 fromy approaching the opposite side: wall 15 of the socket.

The specic clamping means `forthe VendV l ofthe side rail v11v may befof any desired .85

which'engages Athe outer-"face ofthey wedgef block 35.- 'The aperture in "theV .wallllG through, lwhichthe?boltf39 passes is preferably 'large enoughA to adinit freely' the washer 40 so thyitthel latter canV be made long 'enough tobring the lnut `38jwell outside fof the socket in an accfessible position.
